To a/ZZ whom ibm/ty concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPlanes, of which the following is a specification.

This invention relates to planes, and especially to that class of toolscommonly known as smoothing-planes, and it has' foritsobject to providean improved supporting and adjusting device for the plane-knife or planeiron, whereby the same can be quickly and accurately adjusted withrelation to the work to be done, and also to provide an improvedclamping device for said plane knife or iron, whereby the same will befirmly held against vibration in the use of the plane.

In the drawings accompanying and formingV part of this specication,Figure 1 is a vertical longitudinal section of a plane embodying myimprovements, parts of saidgure being shown in full lines. Iiig.l 2 isalplan view of a portion of the plane, illustrating certain features ofthe construction, a part thereof being shown in section. Fig.` 3 is atransverse section taken in line ct a, Fig. 1, looking toward the righthand; and Fig. 4 is a top view of the improved clamping device detached,a part thereof being broken away.

Similar characters designate like parts in all the figures of thedrawings.

This improved plane, in the preferred form thereof herein shown,consists of a suitable stock or body, designated generally as 100,adapted for co-operating with those elements in which my inventionparticularly resides. This stock 100 is shown as providedwith a suitablehandle at one end thereof and with the usual actuating-knob at theopposite end thereof. The stock has formed in its sole the usualtransversemouthlO, the forward wall of which is designated 11 and therearward wall as 12. Y

In the rear of the mouth 10 the stock is provided with a plane-ironcarrier seat or support 13 of aconstruction suitable for the purposeherein set forth. This carrier seat or support 13 is shown as having itsupper face 14 thereof preferably on a plane parallel with the sole ofthe stock and thereby forms a horizontal carrier-support for theplane-iron car- Senal No. 551,754. (No model.)

rior-bracket and is preferably integrally connected with said stock andextends transversely entirely across the stock, being united with themouth of the plane by means of an inclined portion 15. This carrier seator support 13 is somewhat thicker in cross-section than the sole of thestock to adapt it to receive the locking devices ofthe plane-iron orknife-carrier hereinafter described. Instead across the stock,theknifecarrier seat or su pport may, if desired,' consistof.a.pair,j0f.lon gitudinal shoulders on a plane parallel with the soleof the stock and extending inwardly a short distance `from the sides ofthe plane. In this case, however, an intermediate horizontal supportmust be provided to receive the locking-devices of. the knife-carrier,hereinafter described. f lWhen' the seat or support 13 is constructed ofa solid member extending entirely across the stock, as is thefpreferableconstruction, said carrier support or seat has a recess 16 thereinforming two parallel longitudinal guideways 17, Fig.'3. A knife orplane-iron carrier or bracket 20 is adjust` ably supported-on thecarrier seatk or support'by means of binding-screws 2l, hereintheguideways 17, and has a recess 18 in its under side to engage theguideways 17 of the carrier support or seat. This carrier-bracket isshown as having a vertically-inclined side 22 relative to the sole ofthe stock, adapted to receive the plane iron or knife 23, and isprovidedat its under sidewith a horizontal bearing-face parallel withtheface 14 of the support .13,-and is` adapted to slide on said carriersupport orseat. The carrier is extended below its horizontal face 14 toform a support 24 for the lower end of the knife, and ispreferablyV-shaped, to permit the under edge thereof to be inclinedparallel withthe inclined portion 15, connecting the mouth of the stockand the carrier seat or support. A suitable adjusting devicefortheplane-iron carrier-bracket, designated in a general way by A, isprovided for adjusting said carrierbracket and thereby the kniferelative to the mouth of the stock, and is shown comprising suitablebracket-arm 26, preferably integrally connected to the stock of theplane, and in the upper end of which a threaded spindle of the seat orsupport 13 extending entirely after described, and is adapted to slidein? o ICO 27, provided with a suitable thumb-nut 28, is.journaled, thescrew end thereof working in a suitable screw-threaded recess in therear side of the carrier. By turning said thumb-nut the carrier-bracketwill be adjusted to the desired position by sliding upon its horizontalsupport or seat toward or from the mouth of the stock.

In order to adjustably secure or clamp the carrier-bracket upon its seator support 13, binding-screws 2l are preferably used and are passedthroughvelongated slots 31 in that por-` tion of the carrier which hasits upper face in a plane parallel with the lower or seat-engaging faceof the carrier-support,in order that the carrier may be moved relativelyto its seat or support without etfecting the positioning of thebinding-screws, and to permit this the carrier is shown as havingrecesses 28 countersunk therein and communicating with the inclined face22 of said carrier. Washers 30 are disposed between the heads of thebinding-screws and the horizontal upper face of the carrier-bracket, andsaid carrier-bracket, by means of the elongated slots 31, can beadjusted in longitudinal direction of the stock by means of theadjusting device A, hereinbefore described. By this particularconstruction and organization of the plane-iron or knife-supportingmembers of the plane iron or knife a perfect adjustment of the plane isobtained, and, moreover, a perfectly rigid support for the plane-iron orknife-carrier bracket is provided. Any suitable means for verticallyadjusting the plane-iron may be used, but is shown as comprising a lever35, pivoted at 36 to the carrier, and having its upper end in engagementwith the capplate 23 for actuating the same toward and from theplane-month, and thereby moving the plane-iron in the same direction.This lever has the usual forked tailpiece 37 engaged by a peripheralgroove in an adjustingnut 38, which works longitudinally upon a screw orthreaded post 39, fixed to the carrier.

As a means for clamping the plane-knife 23 and its usual cap-plate 23 inposition, I have provided an improved clamping device, designated in ageneral way by B, and which comprises a main clamping-lever having asupplemental clamping-lever connected therewith, and thereby forming adouble clamping-lever, which, in the preferred form thereof, is shownconsisting of a main clamping-lever 40, workin g on a fulcrum-screw 41,disposed on the carrier-bracket and having pivoted to its upper end theusual actuating cam-lever 42, having its cam-face 43 in operativeengagement with the upper face of the cap-plate.

Pivotally connected to the main clampinglever 40, at any suitable placethereon, and projecting beyond the lower clamping end of said lever, isa supplemental elamping-lever 45 ot' any suitable construction adaptedfor the purpose herein set forth and of comparative flexibility relativeto the main clampinglever. The main elampingvlever 40 has recesses 46,and is provided with laterally-projecting pins or studs 47, upon whichthe supplemental clamping-lever is adapted to swing by means of suitableears or lugs 48, having apertures therein adapted to engage said pins orstuds. As a means for adjusting this supplemental lever, the upper endthereof is provided with a suitable adjusting device, herein shown as aset-screw 49, adapted to work on the upper surface of the main clamping'lever. This supplemental clam pin g-lever also has an 'elongatedaperture 5l to permit the fulcrum-stud 4l to be adjusted into position.By means of this improved clamping device, one lever of which is adaptedto engage the cap-plate at a point beyond the clamping end of the otherlever, the knife or plane-iron is firmly held at different points nearits working end, and vibration thereof in the use of the plane issubstantially eliminated.
